If you're exporting to a 32-bit (signed or unsigned) integer format, the obvious choice for null is 0x80000000. That's what GRASS uses internally, so it can never occur as a legitimate value (if a computation ends up producing that value, it will get treated as a null in all regards). -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
